Maintaining a functional and reliable surface—whether it’s a rural driveway, access road, or hardstand—is essential for safety, longevity, and property value. But knowing whether to grade, regrade, or fully resurface your property can help you avoid ongoing issues and manage long-term costs.
At Victor Harbour Road Tech SA, we assist property owners, businesses, and local authorities across Victor Harbour and surrounding areas with high-quality surface maintenance. Below, we outline how to decide when each option is appropriate and what signs to watch for.
What’s the Difference?
Understanding the differences between grading, regrading, and resurfacing is key to choosing the right solution.
Grading
Grading is the process of smoothing the existing unsealed surface using specialised machinery. This helps restore evenness, improve drainage, and eliminate small imperfections like ruts or shallow potholes.
Regrading
Regrading is a more intensive version of grading. It involves reshaping the underlying sub-base and may require adding new material to adjust the slope or elevation. This method is used when the structure beneath the surface is no longer sound.
Resurfacing
Resurfacing applies a new layer of material—such as asphalt or spray seal—over an existing surface. It’s generally required when the current surface has deteriorated significantly or is no longer fit for purpose.
Signs It’s Time to Grade
Grading is typically part of routine maintenance for rural or unsealed roads. You may need grading when:
- Potholes or corrugations begin to form
- The surface becomes uneven or bumpy
- Water starts pooling after rainfall
- Loose gravel collects at low points or along the edges
Grading helps restore usability and prevent further deterioration, especially in areas affected by high traffic or weather extremes.
Signs It’s Time to Regrade
Regrading is often necessary when the issues go beyond surface-level wear. You may need regrading if:
- The base material has eroded or become soft
- Drainage issues continue despite surface grading
- Water runs in the wrong direction or settles in new areas
- There’s recurring surface failure after each repair
Regrading involves a deeper rebuild, which allows for proper water flow and base stabilisation, creating a solid platform for long-term performance.
Signs It’s Time to Resurface
If your driveway or road is sealed but showing extensive signs of wear, resurfacing may be the best approach. Consider resurfacing when:
- Cracks have spread or formed a “crocodile skin” pattern
- Potholes reappear despite patching
- The surface has faded, become brittle, or lost texture
- It’s been more than a decade since the last resurfacing
Resurfacing creates a strong, smooth, and durable layer that not only improves performance but also enhances the appearance and value of your property.
How to Choose the Right Approach
Choosing between grading, regrading, or resurfacing depends on a combination of surface condition, drainage performance, base stability, and usage type.
If the surface still has a stable base and just needs levelling, grading is usually enough. If water drainage is poor or the base has shifted, regrading becomes necessary. When the sealed layer has worn out or is compromised by cracks and potholes, resurfacing is the most effective solution.
At Victor Harbour Road Tech SA, we inspect each site to identify the most cost-effective and durable option, tailored to your property’s conditions and requirements.
Conclusion
Choosing the right time to grade, regrade, or resurface your property can significantly reduce maintenance costs, improve access, and protect your investment. By addressing surface issues early, you can avoid more expensive reconstruction in the future.
